I used this box to protect my neon tetras’ fry. The fry stayed safe from larger fish and grew well. It’s easy to hang and clean. Great for breeding setups.

Works perfectly for my injured guppies. The water flow from the tank helps them adjust. I didn’t have to worry about them getting eaten by other fish.
